ICND v2.0—5-8 Summary • RIP is a distance vector routing protocol that uses hop count as the metric for route selection and broadcasts routing updates every 30 seconds. • RIP has maximum of 15 hop counts. • RIP is a classfull routing protocol, dosen’t supports VLSM. • Administrative distance of RIP is 120. • It comes in two types Ver 1 and Ver 2. • V2 supports VLSM,classless and route summarization.
Editor's Notes
- Purpose: This chapter introduces the Cisco IOS™ CLI on the Catalyst® 1900 switch and router. Timing: This chapter should take about 2 hours to present. Note: The Catalyst 1900 switch only has a subset of the router Cisco IOS commands available. Contents: Introduction to Cisco IOS. Explain to the student what is IOS? Cisco Device startup procedures in general. IOS configuration source. General introduction to the IOS CLI. Cat 1900 switch startup procedures. Intro to Cat 1900 CLI. This part covers the basic configuration on the switch, like setting the IP address and hostname. More details about the various Cat 1900 switch configuration commands are explained in Chapter 6 and 7. Router startup procedures. More details on the router startup process is discussed in chapter 5. Router IOS CLI.
- Purpose: This figure presents general information about RIP. Emphasize: The figure shows a network. The arrows highlight the path RIP selects. RIP selects the best path based on the shortest hop count, so it ignores the path with the faster T1 links. Be sure that you do not disparage RIP. It was developed in a homogeneous network. If everything is connected via a single media type, then bandwidth-based metrics reduce to hop count. In some cases, RIP is more appropriate than other protocols. It is extremely well tested.
- Purpose: This figure presents the Cisco IOS™ commands used to configure RIP. Emphasize: The figure shows the router rip command and the network network-number command. A proper understanding of these commands will save many problems in the lab. Point out that the network statement contains no subnetting information. Networks are directly connected and are specified as a Class A, B, or C network number. Transition: An example of configuration follows.
- Purpose: The figure shows how the RIP commands operate on the example network. Emphasize: An administrator only specifies directly connected networks that should be published to other routers. Without the network command, nothing is advertised. With a network command, the router will advertise every subnet within the Class A, B, or C network specified in the configuration.
- Purpose: This figure shows how the show ip protocol command is used to monitor RIP operation. Emphasize: The command displays the routing protocols that are active on the router for IP. It also gives network and timer information. Point out the timing information. Point out the list of networks for which the router is injecting routes. Point out the administrative distance metric.
- Purpose: This figure displays the show ip route command, which displays the contents of the router’s IP routing table. Emphasize: Discuss the IP routing table in detail. Show the locations of the hop count (metric) and the administrative distance (120). Discuss the following fields: R—Refers to routes learned from RIP. via—Refers to the router that informed us about this route. 00:00:07 timer value—RIP updates are every 30 seconds. Ask, “How long until the next update?” The interfaces used for the best path
- Purpose: This figure shows the debug ip rip command. Emphasize: Explain that debug commands also provide information for monitoring IP. The first highlighted line lists the source of the updates. The router returned information about two destinations. The last highlighted line shows the broadcast address to which the router sent updates.
- Purpose: This slide discuss the initial configurations on the routers and switches. Note: There is no setup mode on the Catalyst 1900 switch.
